Hollyland Walkie-Talkie Converter Kit with 2-Core Walkie-Talkie Connection Cable

Hollyland Walkie-Talkie Converter Kit (with 2-Core Connection Cable)

The Hollyland Walkie-Talkie Converter Kit (specifically the Converter-2C bundle) is an enterprise-grade hardware bridge designed to seamlessly unify dual-contact analog commercial radios (walkie-talkies) with modern full-duplex wireless intercom networks.

In large-scale productions, event management, and broadcast environments, security personnel and facility coordinators often rely on simplified, high-power analog radios, while the media production crew operates on dedicated digital intercom loops. The Converter-2C bridges this gap, allowing direct communication between these separate systems. It routes the walkie-talkie signal into any master station or intercom hub via a standard 4-wire interface, operating without lag or manual patching.

1. Universal 4-Wire System Integration

The central processing node of the kit is the Walkie-Talkie Converter-Box (HL-CB01). It acts as an impedance-matching, audio-leveling translator:

• Broad Ecosystem Matching: The box features standard dual 3-pin XLR (Audio In/Out) terminals alongside an RJ45 port layout. This allows it to patch natively into any production matrix or hub that utilizes a 4-wire audio interface.

• Hollyland Native Synergy: It pairs out of the box with premium digital intercom platforms, including the Solidcom C1 / C1 Pro Hub Stations, Syscom 1000T, and Mars T1000 networks, extending their reach to analog radio channels.

2. Intelligible VOX Automation & PTT Support

Bridging an analog "one-at-a-time" radio channel into an "always-open" full-duplex digital matrix requires smart voice gate controls to prevent noise loops:

• Hardware VOX Voice Activation: Features an adjustable voice-activated (VOX) threshold switch ($>-23\text{ dBu}$). When a digital intercom user speaks, the converter automatically senses the incoming signal, keys the walkie-talkie transmitter instantly, and passes the voice line through cleanly.

• Tactile Push-to-Talk (PTT) Modes: Beyond automated threshold gating, the converter supports traditional, manual PTT control overrides, maintaining complete physical command over when the analog radio frequency is being locked or broadcasted to.

3. The 2-Core/2-Pin Walkie-Talkie Connection Cable

The defining component of the Converter-2C variant is the included 2-Core Walkie-Talkie Connection Cable. This custom-engineered jumper handles the physical cross-patching duties for single-channel or entry-level commercial radio configurations:

• Single-Prong/Dual-Contact Configuration: The radio-side termination features a streamlined 2-core plug (typically a single-pin configuration utilizing two isolated internal copper conductors for common audio signals and shared PTT ground loops). This layout is widely used by ultra-portable or specialized heavy-duty commercial radios.

• Industrial K-Type LEMO Connector: The converter-box end of the cable utilizes a heavy-duty, locking 5-pin K-Type LEMO plug. This robust connector prevents accidental disconnections if a technician snags the cable while managing gear racks or field setups.

• Long Reach: Measuring exactly 1000 mm in length, the cable offers plenty of slack to comfortably mount your 2-core walkie-talkie transceiver next to the converter frame on a rack panel or light stand.

4. Studio-Grade Audio Processing Architecture

Connecting disparate radio networks often causes massive volume spikes, impedance hums, or sharp digital clipping. The internal circuitry of the Converter-Box actively mitigates these anomalies:

• Linear Passband Clarity: Preserves vocal fidelity across a wide frequency response range of 100 Hz to 20 kHz, maintaining an overall total harmonic distortion (THD) of less than 1% for crisp speech transmission.

• Balanced Signal Isolation: Delivers a safe, optimized audio signal path with an input threshold handling capability of up to $18\text{ dBu}$ and a Signal-to-Noise Ratio (>55dB}). This ensures your communication remains clear and free from hums, ground loops, or high-frequency analog hiss.
